I am working with John at CRT to build a 2nd gear start 727. 1.45 first gear for my twin turbo car. He already has a 2nd gear start billet valve body with the brake operable in 2nd. I have a A&A straight cut 2.45-1.45-1 gear set. You could use a 2.77-1.57-1 helical gear set to get a little more SLR if you need it.
thank you for what you are trying to do and not giving into the power guide ( taxi cab trans )
